Redstone Arsenal is a mod by Team CoFH which adds different tools and weapons that utilize Redstone Flux - a type of energy added by Thermal Expansion. All these tools can be charged with energy using an Energetic Infuser, Flux Capacitor or equivalent from other mods. They can also be enchanted, and are the same as gold in that regard. These tools can be empowered and quelled at will. When empowered the RF cost goes up dramatically.
